| Descripción : | The behavior of microporous nitroprussides in the presence of ammonia, both in anhydrous and hydrated states,was studied using ammonia adsorption isotherms and IR,M¨ossbauer and XRD techniques. In their anhydrous state these materials behave as a zeolite for ammonia adsorption, however when structural water is present a decomposition process was observed. The crystallization or adsorbed water is used by ammonia to form NH+ 4 and OH−, creating basic conditions where the structural building unit [Fe(CN)5NO] loses the NO group to form a pentacyano complex. This leads to the formation of mixed salts, M(NH4)[Fe(CN)5]·xH2O. For ferrous nitroprusside the formed OH− ion competes with the complex anion for the iron(2+) cation which is removed, then oxidized and finally observed as a ferric oxyhydroxide, FeOOH. |
